The transport airplanes are also there. Aid has been dropped from them to Gaza and some of it killed people and it was generally a drop in the bucket compared to aid entering via land. Instead of fantasizing about F35s which are a very expensive way of delivering incredibly small amounts of things we should fantasize about getting more trucks to deliver stuff where it's cheap and massive amounts. That's a lot more tractable and achievable. We can also fantasize about what peace looks like and it doesn't look like dropping things from F-35s, that's generally what you do when you gave up on peace (which holds for both bombs and supplies).

Since the "ceasefire" about 21,000 tons of medical aid has entered Gaza. The amount of water already delivered is also immense and if you were to replace/complement this with desalinization you need to build a proper desalinization plant or repair the one that was already there. Let's fantasize about what more is needed and working with the different parties to get there. An F-35 can carry about 10 tons. So you'd need 2000 sorties to deliver a similar amount under the most ideal conditions each sortie costing something like $100K. A C-130 about 20 tons and has about x3-5 less operational cost per hour. It's not just about carry capacity it's about systems to deliver them (like parachutes or whatnot) which a C-130 is already fitted with. So for air delivery of stuff (which is ridiculously low volume and expensive) the C-130 is the preferred choice between the two. We also happen to have an inventory of things on pallets that are ready for C-130s. It's still not a great choice anyways. A commercial truck can carry 40 tons and operating costs would be something like $100 and the trucks are also already there and moving. If we need to get more of those that's what we should work on (and for all those options you need to work with the people on the ground and in the region. The problem isn't capacity/capability it's the politics and the situation on the ground.

If we're fantasizing maybe start with Lennon's "Imagine no religion" ;)
